AI Technical Summary
Existing heavy ion mixed beam diagnostic methods cannot meet the requirements for real-time measurement of beam energy and flux rate, and the lower limit of the ion composition resolution capability of active detectors is limited, resulting in high measurement uncertainty.
A detector system based on the ToF-E method is adopted, which combines time-of-flight resolution, energy resolution and simulation calculations to obtain the flight time and energy of ions through a microchannel plate and a plastic scintillator detector, and to measure the ion species and proportion in real time using τ-E two-dimensional spectroscopy.
It enables real-time measurement of the type and intensity of heavy ion mixed beams, supporting the evaluation of the irradiation performance of electronic components and shielding materials in deep space exploration and aerospace missions.
